JAMES OARMIOHAEL, OF OSH AWA, ONTARIO, CANADA.

CINDER-SIFTER.

SPECIFICATION forming part of Letters Patent No. 313,054, dated March 3; 1885.

Application filed June 2.3, 1884. (No model.)

To all whom, it may concern Be it known that I, JAMEs CARMICHAEL, of the town of Oshawa, in the county of Ontario, in the Province of Ontario, Canada, gentleman, have invented certain new and useful Improvements in Cinder-Sifters; and I do hereby declare that the following is a full, clear, and exact description 'of the same.

The :invention relates to certain improvements in a cinder-sifter patented by me in Canada on the 5th of April, 1884, No. 19,061, and for which an applicationis now pending in the United States Patent Office, tiled April 3, 1884, Serial No. 126,510; and the object of the present invention is to provide simple means for securing 'the ash-pan to the sifter and effective means for more thoroughly and quickly separating the cinders from the ashes; and it consists in the peculiar combination and the construction and arrangement of parts,

hereinafter more fully described and claimed.

Figure I is a cross-section of my improved sifter placed within the box in which the sifting takes place. Fig. 2 is a perspective detail ofthe sifter proper complete, showing a portion of its end broken away to exhibit its interior construction. Fig. 3 is a perspective detail of the cage forming the sifter with one of its ends removed. Fig. 4 is an enlarged perspective detail of one of the notched brack- Fig. 5 is a perspective detail ofthe bar employed for supporting the ash-pan.

It will be noticed that Fig. I is a cross section or end section, the door, which is seen partially broken away, being intended to be on the far side or end of the box A, which is rectangular in shape,and has placed at its bottom the ash-pan B, which can readily be rcmoved when full.

The sifter proper is composed of semicircular ends C, preferably made of wood,and connected together by a netting, D, as represented. The ash-pan E, held in position as shown, completes the ash-sifter. This is intended to represent the ordinary' stove ashpan, and is carried from the stove and placed into the sifter without being emptied.

F represents a latbottom formed of netting and connecting the flat sides of the ends C together.

G isa rectangular hole made in the center ofthe bottom F. To guide the cinders into rocking motion of the sifter will be arrested and broken up, as it were, .so as to separate the ashes from the cinders, allowing the latter to fall into the ash-pan E when the sifter is -placed in the position it is shown in in Fig. l. -J are brackets secured, as shown, one to each end C. Each bracket J forms a pivotspindle, which iits in bearings made in the box A, to permit the sitter to be revolved within the said box. It will be noticed that the long arm of the bracket J has a series of curved notches, j, which notches are intended to allow for ash-pans E of various depths to be placed in position.

K is a bar provided with ends arranged to tit into the notches j. These ends have extensionlips k cast on them, so that while they readily fit and may be removed from the notchesj they will not revolve entirely around the said notches.

Zis a crossbar formed in the center of the bar K, and provided for the purpose of enabling the board L to be iixed to the bar K.

wider than there is any real necessity for, but this is of no consequence, as it may be made either narrow on, the full width of the sitter, as desired.

M is a wedge placed between the board L pose of forcing the said ash-pan up against thc bottom of the sifter.

W'hen about to work the sitter, the operator ascertains the depth of the ashpan E which is to be placed into the box. Having ascertained this depth, he adjusts. the bar K into the particular notches j, which will leave suf ficient room between the top of the board L and the bottom F of the sitter to allow the free passage of the pan E. Vhen this is placed in position, the wedge M is driven in on one side between the board L and the bottom of In the drawings I have shown the board L and the bottom of the ash-pau E for the pur- 9o IOO the ash-pan E. The other side of the board L will offcoursetilt up and come in Contact with the 'opposite'side ofthe ash-pau E, thus forcing up evenly the top edge ofthe said ashpan against the bottom F. Vhen the ash-pan is thus secured,the door of the box A is closed and a rocking or revolving motion is given to the sifter, causing the ashes to fall into the ash-pan B, while the cinders remain in the netting, and when thoroughly sifted are carried backinto the ash-pan E by bringing the sifter into the position it is shown in in Fig. l.

I am aware of the Patent No. 100,421, which shows wires connecting the two ends of the sifter and serving as supports for the netting thereof, and make no claim to such construction asfforming part ot' my invention, for said Wires'have nopractical effect in arresting and breaking up t-he ashes, which is the object of 'my'wi're's I. I'd'eem it important that these wires be arranged at a distance from the nettlng, for where they are arranged in close r proximity thereto they have little or no effect inarresting and breaking up .the ashes. i' What I claim as my invention is- 1. A sifter comprising the semicircular ends C, the netting D, bottom F,"r i'd'the slanting pieces of netting H, arranged `substantially as and for the purpose specified.

2. A sifter having the ends C, the netting D, and netting F, having the hole G made in the center of the latter, in combination with the brackets J, having notches j, the bar K, board L, the Wedge M, and the ash-pan E, substantially as and for the purpose specified.

3. The sifter provided with the brackets J, having the notches j, in combination with the bar K, having projecting lips k formed on its end to prevent the said bar from completely revolving in the notches.

4. The sifter provided with the brackets J, havingvnotchesjfin combination with the board L, fixed tothe cross-bar Z, and the bar K, having the cross-bar lZ, substantially as and for the purpose specified.` y Oshawa, June 14, 1884.
